1.首先需要引入jquery
2.
<body>
a<input type="text" id="a"><br>
b<input type="text" id="b"><br>
<button onclick="test()">click</button>
<button onclick="c()">clear</button>
<script>
$("input").each(function(){ //遍历input标签给其赋值
var key = $(this).attr('id');
$(this).val(localStorage.getItem(key));
})
function test(){
$("input").each(function(){ //遍历input标签将第一次的值存到localStorage中
var key = $(this).attr('id');
var value = $(this).val();
localStorage.setItem(key,value);
})
}
function c(){ //清除本地存储
localStorage.clear();
}
</script>
</body>
